If you notice an earthy or musty scent when using water from your well or tap, it might raise questions about radon levels in your household water supply. In Oneida County, New York, the local aquifer samples reveal measurable radon presence, giving residents a basis to consider treatment options.
How Water Treated for Radon Differs at Your Tap
When water passes through a dedicated radon reduction system such as the C-Series Radon in Water Filter, the treated water you use will exhibit significantly reduced radon activity. This results in less radon transferred to your indoor air via water use and lower radon concentrations in water-related appliances. You may notice improved peace of mind regarding water safety, although radon itself is odorless and tasteless, so sensory changes are minimal.
Distinguishing Radon from Commonly Confused Water Issues
Radon differs from other water concerns typically mistaken for it, such as iron staining or sulfur odors. While iron can discolor fixtures and sulfur often causes a distinct rotten egg smell, radon is a radioactive gas that does not alter taste, color, or odor of water. Recognizing these differences is important to select an appropriate treatment method.
Ruling Out Other Causes Before Testing for Radon
Before pursuing radon-specific water treatment, start by evaluating your water for more common, less costly issues:
- Check for staining or discoloration that may indicate iron or manganese
- Note any sulfur smell, often from hydrogen sulfide
- Confirm that plumbing fixtures and ventilation systems are functioning properly
After excluding these factors, a laboratory test is the most reliable next step to identify radon levels in your water.
Understanding Certified Laboratory Radon Test Reports
Certified laboratory results for radon in water express values in picocuries per liter (pCi/L). Testing your own well water will provide a specific measurement indicating the radon-222 concentration. These reports allow you to assess your water’s radon content precisely and guide decisions on treatment needs.
Interpreting Oneida County Aquifer Radon Measurements and Federal Standards
The U.S. Geological Survey collected six test results from four wells within Oneida County’s aquifer between 2013 and 2022 showing radon-222 levels ranging from 16.0 to 120.0 pCi/L, with a median of 88.5 pCi/L. None of these results exceeded federal action levels set to protect health, confirming the aquifer as a known but compliant source. It is important to emphasize that these area-wide figures do not predict your household’s water radon concentration; only your own test can determine that.
While radon presence in water is a natural occurrence, reducing it can lessen indoor air radon levels and associated risks. The C-Series Radon in Water Filter ships ready to configure for residential water systems and can help address radon when testing confirms elevated levels.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-08-15. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of Radon-222 in the aquifer (Oneida County): 6 results from 4 wells, median 88.5 pCi/L, range 16.0-120.0 pCi/L; none above any federal threshold
